In modern warfare, communication serves as the eyes and ears of battlefield command, and its reliability directly impacts the outcome of battles. Field fiber optic patch cord cables have become a crucial means of ensuring frontline communication. Because fiber optic cables are frequently interrupted by artillery fire, emergency response teams must risk their lives to repair them. Field fiber optic patch cords are fiber optic connection components specifically designed for complex field environments. They possess high strength, rapid deployment, and adaptability to extreme environments, and are primarily used in military communications and emergency repair scenarios.
Field Fiber Optic Patch Cord Cable Features
Field cables typically adopt an aramid yarn reinforcement layer and a polyurethane outer sheath, making them lightweight and possessing high tensile strength (e.g., the GYFB/D model can withstand repeated winding and unwinding). They are also protected by a layer of bulletproof fiber or flame-retardant material (such as LSZH), supporting operating temperatures from -40℃ to 70℃, and are moisture-proof and corrosion-resistant.
Field Tactical Cable Structure
Field tactical cable generally use an aramid yarn reinforcement layer and a polyurethane outer sheath, which are lightweight and have high tensile strength, such as the GYFB and GYFD model, which can withstand repeated winding and unwinding. At the same time, they are protected by a layer of bulletproof fiber or flame-retardant material such as LSZH, supporting an operating temperature of -40℃ to 70℃, and are moisture-proof and corrosion-resistant.
GYFD Field Cable
Supports 2/4/6/8/12 cores, high-strength and high-toughness TPU outer sheath, imported aramid fiber to increase tensile strength. Application: Quick deployment and retraction of canvas cabling, temporary field operations, stage cabling, live streaming, and military communications and emergency repair scenarios.
GYSFJU Armored Field Cable
Supports 2/4/6/8/12 cores; armored structure enhances rodent resistance and pressure resistance.
Application: Harsh environments such as oil fields and mines; resistant to oil and chemical corrosion.
GYFB Field Cable
Nylon tight-buffered fiber + aramid reinforcement layer + polyurethane sheath, supports 1-6 cores.
Features: Lightweight (3.3-5.0mm diameter), high tensile strength, suitable for tactical drag cabling.
Core Application
Due to their unique structure and characteristics, field fiber optic cables and patch cords are primarily used in the following scenarios:
- Military Communications: Used for tactical command and UAV data links, resistant to electromagnetic interference and supporting 10Gbps high-speed transmission.
- Emergency Rescue: Rapid restoration of temporary communications during disasters such as earthquakes and floods (e.g., the Henan rainstorm emergency repair case).
- Field Exploration: Real-time data transmission and remote monitoring in oil fields, mines, and other similar environments.

How to choose the right base station fiber optic patch cord?
Different types of base station CPRI cable have different structures, the number of optical fibers, the outer sheath material, and the tensile strength, so they are suitable for different application scenarios.
| Model | Fiber count | Jacket material | Tension strength | Application scenarios |
| GYFB/B | 1-6 | Polyurethane | 500N | Tactical dragging |
| GYFD/B | 4-12 | Armored TPU | 800N | Industrial emergency repair |
| DLC-DLC | 2 | Flame Retardant LSZH | 600N | Base station remote deployment |
Note: The specific model selection needs to be determined based on the transmission distance (e.g., single-mode supports 10Gbps@20km) and environmental requirements (e.g., temperature range -40℃~70℃).
